It doesn’t sound aggressive or grabby… it’s always more ‘polite’ and holds together fairly well. At the other extreme it doesn’t sound bad, but it doesn’t sound great either. There’s no grit or character in that regard. Its sweet spot is 2:1 or 4:1 with 2-4dB of compression and maybe 6dB at most (at least how I’d use it).
It’s not the compressor I’d want to slam something, then mix it back with the original. I prefer things more along the lines of a distressor and for that I’m fine with software like Arouser, Kush Novatron or several others. But that might be my personal limitations as I’m coming at this much less as a single part mixing tool, but rather 2 bus/mastering.
